安卓ios开发尺寸对应关系

 1、  Android与ios尺寸对应关系：

        [email protected]

        drawable-mdpi=iphone@1x

        [email protected]

        drawable-xhdpi=iphone@2x

        drawable-xxhdpi=iphone@3x

        drawable-xxxhdpi=iphone@4x

2、drawable文件夹下对应的安卓屏幕分辨率：

3、dp与px对应关系：

4、mipmap文件夹（根据Android官方的描述，mipmap仅仅用于存放APP启动图标）：

 

5、代码

public class DensityUtil {

   public static final float getHeightInPx(Context context) {
      final float height = context.getResources().getDisplayMetrics().heightPixels;
      return height;
   }

   public static final float getWidthInPx(Context context) {
      final float width = context.getResources().getDisplayMetrics().widthPixels;
      return width;
   }

   public static final int getHeightInDp(Context context) {
      final float height = context.getResources().getDisplayMetrics().heightPixels;
      int heightInDp = px2dip(context, height);
      return heightInDp;
   }

   public static final int getWidthInDp(Context context) {
      final float height = context.getResources().getDisplayMetrics().heightPixels;
      int widthInDp = px2dip(context, height);
      return widthInDp;
   }

   public static int dip2px(Context context, float dpValue) {
      final float scale = context.getResources().getDisplayMetrics().density;
      return (int) (dpValue * scale + 0.5f);
   }

   public static int px2dip(Context context, float pxValue) {
      final float scale = context.getResources().getDisplayMetrics().density;
      return (int) (pxValue / scale + 0.5f);
   }

   public static int px2sp(Context context, float pxValue) {
      final float scale = context.getResources().getDisplayMetrics().density;
      return (int) (pxValue / scale + 0.5f);
   }

   public static int sp2px(Context context, float spValue) {
      final float scale = context.getResources().getDisplayMetrics().density;
      return (int) (spValue * scale + 0.5f);
   }
   public static String toScreenInfo(Context context) {
      DisplayMetrics displayMetrics = context.getResources().getDisplayMetrics();
      return "屏幕密度："+displayMetrics.densityDpi+"-----"+"屏幕分辨率："+displayMetrics.widthPixels+"*"+displayMetrics.heightPixels;
   }
}
